I pulled this, but then I unpulled it, because this doesn't work for
me AT ALL. I get

   ERROR: modpost: "kvm_arch_has_irq_bypass" [arch/x86/kvm/kvm-amd.ko]
undefined!

when building it. I assume it's due to the change in commit
73e0c567c24a ("KVM: SVM: Don't update IRTEs if APICv/AVIC is
disabled") but didn't check any closer.

I think it's literally just because that symbol isn't exported, but I
also suspect that the *right* fix is to make that function be an
inline function that doesn't *need* to be exported.

So I'm not going to add the trivial EXPORT_SYMBOL_GPL() line, since I
suspect the real fix is different.
